The MC list of parts—music center or master of ceremonies?—includes an AKM AK4113VF S/PDIF receiver and Atmel AT91 MPU; four 24/96 vintage multi-bit BB PCM1704-J converter chips; a Xilinx Spartan field-programmable gate array; a BB/TI PGA2310 digitally actuated analog volume IC; two clocks for the 44.1/48kHz sample-rate families; a 24-bit/100MHz DSP chip; two Chinese PE65612 pulse transformers; two BB INA103 6MHz opamps to sum the symmetrical DAC outputs to single-ended for analog filtering and DC suppression (the final XLR outputs get an additional re-symmetrizing stage); two Takamisawa relays; Adum 1401 chip-based digital isolators; and seven positive/negative voltage regulators from On Semiconductor's LM337T/317T range. There are also four small toroidal power transformers, the usual caps and resistors and obvious sub partitions by means of discrete bays and compartments milled out of the solid aluminium cover stock cum heatsink (the outer scalloping is fully randomized and dissimilar from deck to deck).

The flip side contains merely the super-shallow CD/ROM drive and strategic damping material.

Remember to select the proper setting for anything above 96kHz USB.

Here are two Burr-Brown operational amplifiers; the volume chip bridged by a relay to be bypassed at 100; and the four quasi NOS D/A converter chips.

Here are the DSP chip, the Xilinx FPGA and one of the two clocks...

... followed by the ARM-based 400MHz Atmel microprocessor with high-speed USB host interface.

Next come four voltage regulators heat-sinked by the casing itself...

... followed by more voltage regulators and an inductor in the power filter section.
